WordPress powers a huge share of the web, which also makes it a popular target for automated attacks. The good news is that most hacks exploit simple weaknesses: outdated plugins, weak passwords and missing backups. This WordPress security checklist gives you 20 practical steps to close those gaps and keep your business website, customer data and search rankings safe.
Key takeaways
- Follow a WordPress security checklist every month: updates, backups, logins and monitoring.
- Most hacks are prevented by the simple items on a WordPress security checklist, such as updated plugins and 2FA.
- Build the WordPress security checklist into your maintenance plan so nothing is forgotten.
Why WordPress security matters for businesses
A hacked website can redirect visitors to spam, steal customer details, send phishing emails from your domain and get blacklisted by Google and browsers. Recovery costs time and money, and the damage to trust can last much longer than the technical clean-up. Prevention is far cheaper than repair.
Updates and software
1. Keep WordPress core updated
Security releases fix known vulnerabilities. Apply minor updates automatically and test major updates on a staging site first.
2. Update plugins and themes promptly
Most WordPress attacks target outdated plugins. Check for updates weekly.
3. Remove unused plugins and themes
Deactivated code can still be exploited. Delete anything you do not use.
4. Only install trusted plugins
Choose plugins with recent updates, good reviews and active support. Never use nulled premium plugins, which often contain malware.
5. Use a supported PHP version
Old PHP versions no longer receive security fixes. Ask your host to run a current, supported version.
Logins and user access
6. Use strong, unique passwords
Use a password manager to generate long, unique passwords for every account.
7. Enable two-factor authentication
2FA stops most account takeover attempts even if a password is leaked.
8. Limit login attempts
Block repeated failed logins to stop brute-force attacks.
9. Give users the lowest role they need
Editors do not need administrator access. Review user accounts regularly and remove former staff.
10. Change the default admin username
Avoid usernames like “admin” that attackers try first.
Hosting and server
11. Choose secure, managed hosting
Good hosts provide server-level firewalls, malware scanning, isolation between accounts and fast support.
12. Install an SSL certificate
HTTPS encrypts data between visitors and your site and is expected by browsers and search engines.
13. Use a web application firewall
A firewall blocks malicious traffic before it reaches WordPress.
14. Disable file editing in the dashboard
Turning off the built-in file editor prevents attackers from injecting code if they gain access.
15. Set correct file permissions
Restrictive permissions on configuration files reduce the impact of an attack.
Backups and recovery
16. Take automatic daily backups
Store backups off-site, separate from your hosting account.
17. Test restoring a backup
A backup is only useful if it works. Test restores every few months.
Monitoring
18. Scan for malware regularly
Automated scans detect suspicious files and code changes early.
19. Monitor uptime
Get alerts when your site goes down so you can respond quickly.
20. Review activity logs
Logs show who changed what and when, helping you spot suspicious activity.
What to do if your site is hacked
- Put the site in maintenance mode to protect visitors.
- Change all passwords, including hosting, database and FTP.
- Restore a clean backup or clean the infected files.
- Update everything and remove unknown users and plugins.
- Request a review in Google Search Console if the site was flagged.
Security and SEO
Google warns users about hacked or unsafe sites and may remove infected pages from search results. Spam pages injected by attackers can also damage your rankings for months. Strong security therefore protects your marketing investment as well as your data. Regular website maintenance keeps both in good shape.
Security for WooCommerce stores
Online stores handle customer accounts and orders, so the stakes are higher. Use a trusted payment gateway so card details never touch your server, keep WooCommerce and its extensions updated, enforce strong customer passwords and monitor orders for unusual activity. Make sure your privacy policy explains how customer data is stored and protected.
Building security into a new website
The easiest time to secure a website is when it is built. A lightweight build with fewer plugins, secure hosting, automatic backups and role-based access from day one avoids most of the problems on this list. Our WordPress development services include security hardening as standard.
A simple monthly security routine
Set a recurring reminder once a month to review updates, check that the latest backup completed and can be restored, look at the user list for accounts that should no longer exist, scan for malware and confirm that your SSL certificate is valid. Review the security plugin’s log for repeated login attempts or blocked attacks, and check Google Search Console for security issues. This routine takes less than an hour for most business sites and catches problems long before they become emergencies.

Frequently asked questions
Is WordPress secure?
Yes. WordPress core is secure when it is kept updated and configured properly. Most hacks come from outdated plugins, weak passwords or poor hosting.
Do I need a security plugin?
A reputable security plugin adds firewall rules, login protection and malware scanning, which is helpful for most business sites.
How often should I back up my site?
Daily backups are recommended for most businesses, and more frequent backups for busy online stores.
What is two-factor authentication?
A second verification step, such as a code from an app, required in addition to your password when logging in.
Can a hacked site hurt SEO?
Yes. Google may warn users, remove pages or lower rankings if your site is infected or hosts spam.
Are free themes and plugins safe?
Plugins and themes from the official WordPress directory with regular updates are generally safe. Avoid nulled or unknown sources.
How do I know if my site is hacked?
